'c dol not herewith claim broadly, as our invention a brakingdevice-having an operating-lever pro'virlcd with a pawl tor rotating a drum carryinga cord through which the brake-shoe is applied to the tire ot' a vehiclewl 1 eel.

We' claim as our invention and desire to secure by lnited States `Letters Patent- 1. .ln a device cl' the character described, the con'lbination with. a revoluble toothed barrel, a sprilnypreesed cheek-paw] '7L iny normal engagementtherewith, and a stop for limitin'g'the rearward movement of said pawl, of a swinging opciating-lever d, a working pawle pivoted to the lever and in normal engagement with said barrel member, a stop Ifor limiting the outward angular movement of said pawl e, and having the lree ends and li. ofthe pawls e and lz', reepectively,a1= ranged to engage with each other to throw them out of action' when the lever -d is sui'li ciently advanced, substantially as described.

2. In a device of the character described, the combination of a revolul ly1noumed toothed member, a swinging' operating-lever d having a lug/arranged to engage a fixed part of the device to form a limit-stop, a pawl e 4)ivoted to said lever 'for rotating the toothedl member in one direction, a stop i coacting with the lever for limiting the u ward or outward swinging,r movement of tljie pawl, a check-pawl 71, for normally holding said toothed n'iember in position against rearward movement the ends el; and 71, of the re-V spective pawls being :cam-shaped so that when brought mtoengafrement with each by the forward movement of the lever bot-h pawls are thereb)7 autoinaticallyv with-1 drawn 'from the toothed member, and a stop for limiting the last-named movements of the check-pawl and lever.

3. ln a device of the character described, the combination of a suitably? mounted ratchet-wlieel member, a swinging operating lever adapted to be actuated by foot-pressure, a sell-dropping` pawl pivoted to and movable with said lever for rotating` the ratchet-wheel in one direction, and having the heel or short end. portion of the pawl provided with a lug or extension e3 adapted to be engagedby the foot of pawl out of engagement with said wheel.

4. In a vehicle provided with Atractionwheels, the coi-nbmation with movablymounted brake-shoes arranged with respect to said wheels, of' brake-actuatingr mecha ism comprising essentially a toothed barrel, a self-1etracti1 xg swinging p awl-c arrving o perat- `mgelever for rotating said barrel, a flexible connection mounted on the barrel and operatively connected with the brake-shoes, a spring-pressed check-pawl normally engaging said barrel, means integral with said pawls for disconnecting them from the barrel by the action of said lever when the latter is advanced beyond its normal working movement, and independent stops for limiting: the angular movements ofthe pawls.
